Question

Find the surface area of the figure. ft

Answer 1

Answer:486
`ft^(2)`

Explanation:

surface area= 6
`l^(2)`

l=9

sa=6 (
`9^(2)`)= 6 x 81=486
`ft^(2)`

Answer 2

486

Explanation:

Hello!

To find the surface area of a cube we use the equation

`S = 6a^(2)`

S is the surface area

a is the side length

Put what we know into the equation

`S = 6*9^(2)`

Solve

S = 6 * 81

S = 486

Hope this Helps!
